One of the most common questions small business owners ask is how much they should spend on marketing.
Spend too little and you may struggle to reach enough potential customers. Spend too much without measuring results and you may put unnecessary pressure on cash flow.
There is no single monthly marketing budget that suits every business. The right amount depends on your industry, profit margins, customer value, competition, growth objectives and the cost of acquiring customers.
This guide explains how to establish a realistic marketing budget and assess whether your investment is producing worthwhile results.
Is there a standard percentage of revenue to spend on marketing?
Some businesses use a percentage of revenue as a starting point for budgeting. Others set their budget based on growth targets, available cash flow or the economics of acquiring a new customer.
Neither approach works equally well for every business.
A percentage-of-revenue approach may be useful for planning, but it does not tell you whether the investment will generate enough leads or profit.
A business with high margins and strong repeat customer value may have different marketing economics from a business with low margins or infrequent purchases.
Use industry benchmarks only as context, not as a substitute for understanding your own numbers.
1. Work out how much a new customer is worth
Start by understanding the revenue and profit generated by a typical customer.
Consider:
- Average sale value.
- Gross profit or contribution margin.
- Repeat purchases.
- Customer retention.
- Cost of delivering the service.
- Sales and operating expenses.
Revenue alone can be misleading. A large sale may produce relatively little profit if the delivery costs are high.
For businesses with repeat customers, the longer-term value of the relationship may also matter, provided those future purchases are realistic and supported by evidence.
2. Calculate your lead-to-customer conversion rate
Your conversion rate helps estimate how many enquiries you need to acquire a customer.
For example, if 20% of qualified leads become customers, you would need approximately five qualified leads for each new customer on average.
If you want to acquire 10 new customers and your conversion rate is 20%, you may need around 50 qualified leads.
This is a planning estimate. Actual results will vary, and your conversion rate may differ between marketing channels and service types.
3. Establish an acceptable customer acquisition cost
Customer acquisition cost (CAC) measures how much it costs to acquire a new customer.
A simple calculation is:
Customer acquisition cost = Relevant acquisition costs ÷ New customers acquired
Depending on the purpose of your analysis, relevant costs may include advertising, agency management, content production, marketing software and other acquisition expenses.
For example, if the total relevant marketing cost is $3,000 and you acquire 10 customers, your acquisition cost is $300 per customer.
Whether that is acceptable depends on the profit those customers generate and the other costs of operating your business.
4. Estimate your required marketing budget
You can work backwards from your customer acquisition target.
Suppose your business wants to acquire 10 new customers per month, and your current data suggests an acquisition cost of $300 per customer.
The implied marketing investment would be approximately $3,000 per month if those results continue.
However, this does not guarantee that spending $3,000 will produce 10 customers. Performance can change as budgets, competition, targeting and demand change.
Use past results to establish an initial estimate, then review actual performance as you go.
5. Separate advertising spend from management fees
When planning a Google Ads or Meta Ads budget, distinguish between the money paid to the advertising platform and the fee paid to manage the campaign.
Your total marketing investment may also include:
- Website design or development.
- Landing page creation.
- SEO services.
- Content production.
- Call tracking and analytics tools.
- Other relevant marketing software.
This distinction matters because a campaign’s advertising budget is not the same as its total cost.
When comparing providers, make sure you understand what is included in each fee and whether additional costs apply.
6. Account for the time required to generate results
Different marketing strategies have different timelines.
Google Ads can create opportunities for relatively quick visibility, provided there is sufficient demand and the campaign is effective.
SEO generally requires a longer-term investment in website improvements, content and organic visibility.
Social advertising, referral marketing and conversion optimisation also have different performance patterns.
Your budget should reflect your immediate lead requirements as well as your longer-term business objectives.
7. Start with a measurable plan
If you’re unsure how much to invest, begin by defining a clear objective.
For example:
- Generate a specified number of qualified enquiries.
- Acquire a target number of new customers.
- Test demand for a particular service.
- Improve the cost of acquiring a customer.
- Increase enquiries from a particular location.
Choose the metrics that will help you evaluate progress and ensure conversion tracking is in place.
Avoid setting a budget without a clear idea of what you are trying to achieve.
8. Review performance before increasing spend
Once your campaigns are running, review lead quality, customer acquisition costs and profitability.
If the results are strong and your business can handle more demand, increasing the budget may be worth testing.
If performance is poor, investigate the causes before spending more. The issue may be targeting, conversion tracking, website performance or the sales process.
Increasing a budget does not automatically increase results in proportion to the additional spend.
